To aZZ whom it may concern;

Be it known that I, EFFINGER E.-WHIPPLE,

a citizen of the United States, residing at,

Utica, in the county of Oneida and Stateof New York, have inventedcertain new and useful Improvements in Supporting Attachments forHarrows; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to certain improvements in riding or supportingattachments for harrows or other soil-working implements.

The objects and nature of the invention will appear hereinafter; and theinvention consists in certain novel features in construction and inarrangements and in combinations of parts,as more fully and particularlydescribed and pointed out hereinafter.

Referring to the accompanying drawings, Figure 1 is a top plan view of atwo-section lever-adj ustment harrow provided with a constructionillustrating an example of my invention. Fig. 2 is a side'elevationthereof, the teeth being lowered, the rear portion of one harrow-sectionbeing partially broken away to show the supporting device. Fig. 3 is aView corresponding to Fig. 2, but showing the teeth elevated. Fig. 4. isa detail perspective of a form of the riding or'supporting attachmentwhich can be employed. Fig. 5 is a perspective of portions of the rearends of the two harrow-sections and of the supporting or ridingattachment. Fig. 6 is a detail view of a portion of the draft-tongue orstick of the attachment, showing adjustable loops for the standards fromthe harrowframe and means whereby said loops can be tightened orloosened to prevent or permit lateral play ofthe standards. Fig. 7 showsa modification whereby loose connections or supports depend from thetongue to the harrow-frame and wherein the front end of the tongue canbe spread or braced against lateral play.

In the drawings a two-section harrow of any desirable construction isshown. Each section is formed with its frame a and rocking tooth-bars b,carrying teeth b. Each section has also lever adjusting or operatingmeans for rocking the tooth-bars to raise and lower the teeth. Any meanscan be provided for this purpose, the ordinary means being shown,comprising the upright lever c, rigid with a tooth-bar and carrying alocking-pawl engaging a segmental rack on the adj ustingbar, pivotallyjoined to standards from the remaining tooth-bars of the section. Thoseskilled in the art understand the operation of such a device. Anevener-bar d can be arranged in front of both of the harrow-sections andindependently coupled to each section loosely or otherwise, according tocircumstances. The draft is attached to the evener bar, although ofcourse it is not necessary to my invention that the evener-bar beemployed. be provided for the front ends of the sections, such asdepending shoes or rollers. The har row-sections preferably are notdirectly coupled together in rear of the evener-bar, so that they canhave certain free up-and-down play, although this is not essential to myinvention.

The riding or supporting attachment comprises a draft-tongue orseat-stick f, arranged centrally of the two harrow-sections in the lineof draftthat is, the stick is preferably arranged horizontally above thespace between the two sections and extending from the front part of theharrow to the after part thereof. The tongue is usually formed of astraight stick or bar with an extension from its front endextendeddownwardly and loosely coupled to a forward part of the harrow. Thedrawings show the front end of the tongue coupled to the center portionof the evener-bar; but coupling to the evenerbar is not essential to theinvention, as the front end of the tongue can be coupled at other.points at the forward portion of the harrow. The rear end of the tongueis carried by a supporting-wheel g, which is usually located in rear ofthe center of the harrow, and the rear end of the tongue is preferablyheld elevated by plates or bars 9', secured rigidly to the tongue anddepending therefrom, with the supporting-wheel mounted in and betweenthem. The tongue carries a seat f, usually arranged'in rear ofthevertical plane, including the axis of the supporting-wheel g,although this location is not essential to the invention. Nor is itessential to Suitable supporting devices 6 can ICO the invention thatthe tongue carry a seat, although such is preferred practically.

Suitable means are provided to support or sustain the inner sides orportions of the harrow-sections at their after parts from said tongue,while the harrow-sections can be and are provided with supporting meansat the after parts of their outer sides or portions such as dependingshoes 72. from the frame, as shown in Fig. 2, or supporting-rollers h,suitably mounted, as shown in other figures of the drawingsso that whenthe teeth of either or both harrow-sections are elevated the tongue willcarry the after part of the inner side of a section, while the outerside and front supports carried by the sections will uphold theremainder of the weight of the frame and parts. Various means can beprovided to partially support the inner sides of the sections from thetongue when the teeth are elevated. For instance, the inner sides of therear portions of the frames of the harrow-sections can be provided withrigid vertical standards '5, preferably parallel and extending upwardlyon opposite sides, respectively, of the tongue and to points above thesame. The tongue is provided with rigid side loops oropenings t",through which said standards pass and reciprocate vertically withincertain bounds, and whereby the tongue is held against excessive lateralplay. The loops can be formed to permit limited lateral tilting or playof the standards, if so desired, whereby the sections can rock laterallywithin certain bounds. The loops can be entirely rigid, as shown in Fig.4, or can be formed of plates mounted and slidable in and out onparallel bolts rigid with the tongue and provided with adjusting-nuts atthe outer sides of the plates, as shown in Fig. 7, whereby the nuts canbe turned up on the bolts to press the plates toward the standards andlimit or prevent lateral play thereof inclependent of the tongue, or onloosening the nuts greater play of the standards and harrowsectionsindependent of the tongue is allowed. Suitable means of variousconstructions can be provided to limit the downward movement of thestandards, and consequently uphold the harrow-sections when a certaindistance below the tongue. For instance, the standards can be providedwith series of transverse holes through which a pin t can be passedabove the loop of the tongue to form a stop against further downwardmovement of the standard and permitting adjustment. The standard couldbe locked or limited in other ways. Also instead of the rigid standardsloose connections, such as shown in Fig. 7, could be employed. In thisfigure chains j are shown attached to the tongue and to the inner sidesof the frames of the harrow-sections to uphold the same. The chains areformed of the proper length or made capable of adjustment to permitindependent upward movement of the sections and yet limit their downwardmovement. lVhere such a loose supporting connection is employed, thefront end of the tongue can be forked or braced and secured to theevcnerbar or other part of the harrow at separated points to hold thetongue against excessive lateral play.

If it is desired to throw the weight of the riding or supportingattachment into the harrow, the standards can be secured to the tongueagainst the movement independently thereof, as by passing the stop-pinsdirectly through the loops and standards.

I do not desire to limit myself to the exact arrangement of independentriding attachment shown nor to the location or method of attachment ofthe seat-stick or tongue f nor to any specific or particular means forsupporting the rear end of said riding or supporting attachment. In atwo-section harrow this arrangement of seat-stick has been found to bevery effective; but it might be changed, and also the standards 2' 'a'are not necessarily secured rigidly to the harrow-sections.

By means of my invention a very simple and elfective and yetlight-riding attachment is provided which is practically independent ofthe harrowthat is, the harrow has the proper or desired play independentof the riding attachment, and the curved spring-teeth can be forced downand the harrow-frame elevated by the rider without leaving his seat-andalso by employing a harrow with frame-supports carried by and movingwith the harrow while a portion of the frame is carried by the ridingattachment many practical advantages are attained.

It is evident that various changes might be made in the forms,constructions, and arrangements of the parts described without departingfrom the spirit and scope of my invention. Hence I do not wish to limitthe illvention to exactly what is described and shown, but considermyself entitled to all such changes as fall within the spirit and scopeof the invention.
